Senior Data & AI Engineer

The Senior Data & AI Engineer will architect and optimize secure, scalable data platforms and deliver machine learning pipelines grounded in healthcare claims and clinical data to support cost, quality, and member/patient outcomes.

Key Responsibilities

• Architect, implement, and optimize data solutions in Snowflake and Microsoft Fabric, including OneLake, Lakehouses, Warehouses, and data engineering pipelines.
• Build ingestion frameworks for batch and streaming sources using technologies such as ADLS, EventHub, APIs, and SFTP, with lineage and governance.
• Manage data security, privacy, and compliance for HIPAA and PHI, including role-based access, masking, tokenization, and deidentification.
• Design conceptual, logical, and physical data models, using patterns such as normalized, dimensional/star, and data vault where appropriate.
• Implement data mapping and transformations for both structured (claims, eligibility, provider, enrollment) and unstructured data (clinical notes, PDFs).
• Harmonize healthcare data using FHIR/HL7/CCDA, X12/EDI 837/835, NCPDP, and CMS standards, including record reconciliation and linking across EHR and HIE sources.
• Develop ML pipelines for risk stratification, cost/utilization forecasting, fraud/waste/abuse detection, quality measure computation (e.g., HEDIS), and care gap identification.
• Operationalize models using MLOps, including experiment tracking, reproducibility, CI/CD, monitoring, and drift detection.
• Leverage LLMs/AI tools for data quality, entity resolution, summarization, and clinical insights, while ensuring safety, bias checks, and auditability.
• Implement data cataloging, lineage, and metadata management (for example, Microsoft Purview or an equivalent approach).
• Set up data quality SLAs, validation rules, profiling, and automated anomaly detection.
• Instrument pipelines for cost, performance, and reliability using mechanisms such as Snowflake resource monitors and Fabric capacities.
• Partner with product owners, clinicians, actuaries, and analytics teams to translate requirements into scalable solutions.
• Create clear documentation, including data dictionaries and mapping specifications, and mentor engineers and analysts.
• Contribute to enterprise architectural roadmaps, reference patterns, and best practices.

Minimum Qualifications

• 8+ years in data engineering/analytics, including 5+ years hands-on with Snowflake (compute, storage, virtual warehouses, tasks, streams, Snowpipe, Time Travel, RBAC, row/column masking, data sharing, Dynamic Tables).
• 2+ years with Microsoft Fabric (including OneLake, Lakehouses, Warehouses, Dataflows Gen2, Notebooks, Pipelines; capacity management).
• Strong data modeling expertise (dimensional/star, 3NF, data vault; surrogate keys, SCD types, conformed dimensions).
• Data integration and transformation proficiency: advanced SQL, dbt or Fabric Dataflows/Power Query M, ADF/Synapse/Fabric Pipelines, and Python for ETL/ELT.
• Experience mapping CMS data (e.g., Medicare datasets, claims/encounters), plus X12/EDI, FHIR/HL7, provider and eligibility.
• Experience with structured data (tables, CSV, Parquet) and unstructured data (clinical notes, PDFs, blobs), including NLP pipelines (optional but valued).
• Machine learning capabilities: feature engineering, model training/evaluation, and deployment (for example, scikit-learn, PyTorch/TensorFlow, Fabric ML/Notebook, Azure ML) with production monitoring.
• Security and compliance experience covering HIPAA and PHI handling, auditing, data residency, and BAAs, including practical access control in Snowflake/Fabric.
• Strong communication skills, including the ability to author mapping specs and lineage documentation and present tradeoffs to technical and nontechnical stakeholders.

Preferred Qualifications

• Interoperability experience with FHIR R4, HL7 v2, X12/EDI (837/835), NCPDP, and familiarity with HIE and EHR integrations (e.g., Epic, Cerner).
• Experience with CMS and payer/provider datasets (Medicare fee-for-service, MA, Medicaid, CCW, APCD, quality programs), including risk adjustment (HCC) and HEDIS measures.
• MLOps and DevOps exposure, including MLflow, DVC, GitHub Actions/Azure DevOps, containerization (Docker), and orchestration (e.g., Airflow, Fabric Pipelines, or ADF).
• Governance tooling experience such as Microsoft Purview (catalog, lineage, classifications) and data quality tools.
• Visualization experience with Power BI and Fabric Direct Lake, including semantic modeling and row-level security.
• Cloud exposure in Azure (ADLS, Event Hub, Functions, Key Vault, Databricks), with optional AWS/GCP familiarity.
• Relevant certifications, including Snowflake SnowPro Core/Advanced and Microsoft Certified roles such as Azure Data Engineer Associate and Fabric Analytics Engineer.
